Breathalyzer Source Code Ruling Upheld

dfn_deux writes "In a follow up to a 2005 story where Florida judge Doug Henderson ruled that breathalyzer evidence in more than 100 drunk driving cases would be inadmissible as evidence at trial, the Second District Court of Appeal and Circuit Court has ruled on Tuesday to uphold the 2005 ruling requiring the manufacturer of the Intoxilyzer 5000, Kentucky-based CMI Inc, to release source code for their breathalyzer equipment to be examined by witnesses for the defense of those standing trial with breathalyzer test result being used as evidence against them. '"The defendant's right to a fair trial outweighed the manufacturer's claim of a trade secret," Henderson said Tuesday. In response to the ruling defense attorney, Mark Lipinski, who represents seven defendants challenging the source codes, said the state likely will be forced to reduce charges — or drop the cases entirely.' ... What this really means is that outside corporations cannot sell equipment to the state of Florida and expect to hide the workings of their machine by saying they are trade secret. It means the state has to give full disclosure concerning important and critical aspects of the case."

    remembering back to Driver's Ed (1979) I think it was said that the human body metabolizes about 1 drink per hour. So if it takes an hour to get a blood sample, a suspect could fail a breath test but pass a blood test just by metabolism. Would a court factor in the time between inital arrest and blood sample collection?

    Yes, alcohol is metabolized at a fairly regular rate. Since the time you were pulled over is known, and the time the test was administered is known, when you combine that with the relatively high accuracy/precision of the blood test you can determine what the BAC was at the time the person was driving.

    What this really means is that outside corporations cannot sell equipment to the state of Florida and expect to hide the workings of their machine by saying they are trade secret

    No, what it means is that corporations that sell equipment THAT PRODUCE EVIDENCE TO BE USED IN CRIMINAL CASES can't hide behind trade secret laws. It's a very narrow set of circumstances. If the machine isn't used to produce criminal evidence, it isn't affected. Things like radar guns and red light cameras could be affected by this ruling. General consumer products are not.

    The breathalyzer is effectively acting as a witness against the defendant in a DUI case. The defendant has a CONSTITUTIONALLY GUARANTEED right to cross-examine witnesses and challenge their credibility and accuracy. In the case of a machine, this can include subjecting the machine's design to scrutiny by a defense expert.

    Seems pretty open & shut to me: if they don't disclose the engineering data necessary to validate the accuracy of the machine, then the evidence produced by the machine is inadmissible.

    Since DUI is based on specific blood alcohol levels, they would have to drop those charges and settle for something where they could get a conviction based solely on the arresting officer's eyewitness testimony (EG reckless driving or other specific moving violations).

I don't drink, but if I did, I'd insist on a blood test for two good reasons: It is going to be the most accurate thing, and arranging for it takes longer, giving your liver more time to reduce your BAC.

    It's not pretty. And this isn't an open source project with a wiki and people contributing to documentation etc. It might have been this one guy who worked there 5 years ago and never made a single code comment.

    The code that does the actual work (the calculations) is probably very small. Most of it is probably written to interface with the device. And unless you are getting their exact device -- or one with identical specifications -- then you're going to have to rewrite that anyway. And I suspect they DO have a patent on the device, even if you did somehow get the code.

    I don't know much about breathalyzers besides what they do. Is the source code really the limiting factor to you making a competing line of breathalyzers? I would think the sensor that measures the alchohol on your breath would be the most expensive and most difficult to manufacture part of the whole thing. Perhaps wrongly I would have assumed the source code would be the third easiest thing to make, behind the case for the thing and the hose you breathe into. In other words, I would have assumed that the source code would have been nothing too secret, while the actual sensor was what they spent a lot of money developing.

    Of course, if the source code were very simple, I guess the company probably would have released it rather than facing the 2 mil fines. Or maybe that's just typical corporate arrogance.

    The parties are not the ones who get to see confidential business information. Their attorneys and experts do. For example, I just worked on a case where both sides had to produce competition-sensitive documents to the other side in discovery. These documents were clearly marked "CBI," and I would have been in very serious trouble if I had sent these to my client. If I had done so on purpose, I could possibly have been disbarred. So no, the criminals probably won't get to see this source code. Their attorneys will give it to their experts, and if they find something really useful, they will ask the judge if they can pretty please use it in open court after stripping away anything superfluous to the reason for which it is being used. That will not be enough for their clients to make a competing product.

    The sensor isn't really anything special anymore. Alcohol gas sensors are commodity item and easily had on the parts market. Typically they just output some analog voltage that varies according to the level of alcohol detected. That voltage is subject to calibration and then runs through an ADC to the actual code that maps voltage directly to some magic BAC number. Up until the voltage output, it's all easily tested. The calibration instructions I'll assume are also easily provided by the manufacturer since they [hopefully] perform calibration or provide instructions on how police should calibrate it. After calibrations, all bets are off. After all, it's the BAC number the device spits out, not the voltage of a discrete sensor, that the law is written around.

    Analysis of the source needs to confirm that the scale of the sensor matches the scale in the source code used to generate that magic number. Imagine if one of them was logarithmic and the other was linear... there would be a lot of innocent people falsely convinced (and, depending on which one, a lot of guilty people could have gotten off).

    Driving with a .08 BAC doesn't mean you're actively trying to cause harm.

    In my opinion getting yourself reaction and judgment impaired and then hopping into the drivers seat is actively trying to cause harm.

    Perhaps it shouldn't actually be a 'criminal offense'. But driving is a privilege not a right, and if you think its ok to get wasted and drive around you should have that privilege revoked.

    Now you might argue that 0.08BAC is too low and that it doesn't affect you or whatever, fine, we can have a debate about what the actual number should be. Although I think 0.08 is in the right ballpark, and there are a number of studies which have shown that as you get drunk your ability to accurately gauge how drunk you are goes down. So the people arguing they are just fine at X BAC are far more often than not straight up wrong.
